Description

ких сигналов колебаний соответственно на низкочастотные и высокочастотные составл ющие колебаний режущего инструмента в диапазонах 0...4 КГЦ и 4...22 КГЦ. Разделенные сигналы поступают каждый по своему каналу в блоки детектировани  6 и 7, затем в интегрирующие цепи блоков 8 и 9 и на сравнивающепоказувающий блок 10, который, сравнива  уровни сигналов низкой и высокой составл ющих колебаний, фиксирует величину износа и выдает сигнал, если необходимо, на управл ющее устройство исполнительного органа станка, который выполн ет корректировку положени  лезви  резца относительно обрабатываемой поверхности.oscillation signals, respectively, on the low-frequency and high-frequency components of the oscillations of the cutting tool in the range of 0 ... 4 KHZ and 4 ... 22 KHZ. Separated signals each go through their channel to detection units 6 and 7, then to integrating circuits of blocks 8 and 9 and to comparative blocking unit 10, which, comparing the signal levels of the low and high oscillation components, fixes the amount of wear and produces a signal, if necessary, on the control device of the executive body of the machine, which performs the adjustment of the position of the blade of the cutter relative to the treated surface.

В процессе резани  лезвие режущего инструмента посто нно подвергаетс  износу (затуплению ) и с увеличением площади износа по задней поверхности увеличиваетс  уровень сигнала колебаний по всему звуковому спектру , причем рост уровн  сигнала колебаний высокочастотной составл ющей протекает интенсивнее , чем низкочастотной составл ющей. Сравнение уровней сигналов колебаний высокочастотной и низкочастотной составл ющих осуществл етс  в блоке сравнени  10, что позвол ет точно измер ть текущую величину линейного износа режущего инструмента.During the cutting process, the cutting tool blade constantly undergoes wear (dulling) and with increasing wear area on the back surface, the level of the oscillation signal increases across the entire sound spectrum, and the increase in the level of the oscillation signal of the high-frequency component proceeds more intensively than the low-frequency component. The comparison of the levels of the vibration signals of the high-frequency and low-frequency components is carried out in the comparison unit 10, which makes it possible to accurately measure the current linear wear of the cutting tool.
